The complete semantic sentence learning machine of multi-mode self-identifying

Technical field

The utility model relates to the complete semantic sentence learning machine of multi-mode self-identifying, is mainly used in Chinese student or the self-study personnel foreign language studying and the foreigner and learns Chinese etc.

Background technology

The study of language is to teach personally by teacher before sound-track engraving apparatus is born always.After having had sound-track engraving apparatus by oneself, people begin by the sound-track engraving apparatus foreign language studying, mainly are exercise hearing.Afterwards, for more convenient, people had invented tape language repeater and various learning machine based on digital technology.

At present, superseded substantially with the method for sound-track engraving apparatus foreign language studying merely.Mainly be with tape language repeater and various learning machine.

1, the behaviour in service of tape language repeater:

Why the tape language repeater also has certain market in today, mainly is because some student's teaching material auxiliary tapes.Say that technically language repeater will be eliminated.Its reason is: the lower tone of A, tape does not have the tonequality of digital memory technology good certainly; The recording capacity of B, tape itself is limited, and the capacity of be far from laser disc and SD card is big; C, tape volume are big, and it is all inconvenient to carry collection; D, tape use analogue technique, are certain to be replaced by digital technology.

Digital memory technology replaces the analog storage technology, and the SD card replaces tape even laser disc, and this is historical trend, is who does not stop.Therefore, tape class language repeater is certain to withdraw from very soon the arena of history.

2, the behaviour in service of various digital class learning machines

Behind the tape language repeater, various learning machines based on digital technology have begun to appear on the market in a large number.And certain market arranged.But be far from popularizing.Trace it to its cause: A: valency height, more than 1,000 yuan at most, seven, 800 yuan at least; B: function embraces a wide spectrum of ideas, poor practicability; C: complicated operation, use inconvenience; D: the function of language learning design is nature inadequately, and hommization is poor.

In a word, digital learning machine on the market is that amusement is many at present, poor practicability, and price height.The open language learning platform of neither one supports that nature can not be popularized in addition.

3, various foreign language learning softwares

In order to help people to learn foreign languages, various foreign language learning softwares are also invented by some companies both at home and abroad.These instruments no doubt have its advanced part, but a common shortcoming is all arranged: must operate on computers.This method obviously is not suitable for numerous students, can only be fit to a few high-end crowd.

In a word, up to now, also there are not a real masses of being fit to, especially student's language learner; More neither one is fit to popular especially student's language learning platform.

The utility model content

Technical problem to be solved in the utility model is in order to overcome above-mentioned deficiency, a kind of complete semantic sentence learning machine of the multi-mode self-identifying that can efficiently improve foreign language listening that organically combines with content to be provided.

The utility model is achieved through the following technical solutions: the complete semantic sentence learning machine of multi-mode self-identifying, comprise shell, be positioned at SD card, loudspeaker, MP3 decoding device and the rechargeable battery of shell, the USB interface that is positioned at case surface, button, it is characterized in that also comprising little processing and control module, little processing and control module is electrically connected with MP3 decoding device and rechargeable battery.

The utility model is owing to adopted said structure, in use, pass through the MP3 format file of breakpoint set handling to the SD card by download, by MP3 decoding device played file, select mode of learning by button, listen to file content by earphone or loudspeaker, provide electric energy by charging module and rechargeable battery.The utility model learning machine compared with prior art, following advantage is arranged: volume is little, capacity is big, can be that the study of automatic different mode is selected by unit with the sentence, has improved effects on hearing greatly.
